Asking the Stupid Questions Since 1971
This article on the Mexico City Subway's lending library got me wondering about urban railways. Again. At one point I wrote to all of the countries that I could think of with urban railways and asked for maps. I was seven. I still have the map from Tokyo.
So what does Mexico City's subway look like? UrbanRail has maps and information on urban railways around the world, as does nycsubway.org. There are more than I expected. (The St. Charles line in New Orleans is a fun ride.)
